I am not sure if we want to list the all possible exception here, but at least indent is needed as below.

I agree that introduces some maintenance hazard keeping doc and implementation in sync, but it could be practical to have it there.

I'd also be fine with just a hint at some general throw behavior here.
So I'd leave it up to any reviewer as I am not too familiar with the style use throughout the rest of the codebase.
